Guide

How to model website ROI

The ROI of a website project is nearly always driven by conversion rate — not traffic. Even a 15% relative CVR lift on modest traffic compounds into serious revenue over 12–36 months. Be honest about the uplift: use a benchmark from a past project, not the biggest number a vendor quoted.

Formulas

Monthly revenue = Visitors × CVR × AOV
Monthly lift = Visitors × CVR × Uplift × AOV
Payback = Project cost / Monthly lift
3-year ROI = ((36 × Monthly lift) − Cost) / Cost × 100
